The percentage composition of the alloy is as follows:
copper- 30%
zinc- 35%
nickel- 100- (30+35) =100-65 =35%
Therefore weight of nickel is 35 % of the 740g:
= 35/100 x 740
= (740x35)/100
= 25900/100
= 259 grams
copper- 30%
zinc- 35%
nickel- 100- (30+35) =100-65 =35%
Therefore weight of nickel is 35 % of the 740g:
= 35/100 x 740
= (740x35)/100
= 25900/100
= 259 grams

Step-by-step explanation:
Copper = 30%
Zinc = 35%
Nickel = 100-(30+35)% = 100-65 % = 35%
:. weight of nickel is 35% of the 740 g :
= 35 × 740 grams
100
= (740×35) grams
100
= 25900 grams
100
= 259 grams
